Usually okay on its own
Cornstarch is generally gluten-free as a standalone ingredient because it is made from corn, not wheat, barley, or rye. Still check the package for wheat starch, modified wheat starch, gluten-containing ingredients elsewhere, and advisory statements about wheat or gluten.
Why it matters
This standalone term is generally not a gluten ingredient, but the full product label still matters.
